Nested Map causes non-default updates to fail with Jason encoder error

Describe the bug If you have a map that has array's of maps e.g.

    summary: %{
      chat_history: [
        %{"content" => "Default system prompt", "role" => "system"},
        %{
          "content" =>

    }

To Reproduce A minimal set of resource definitions and calls that can reproduce the bug.

pull down: https://github.com/nheingit/ash_postgres_repo_error

Create the database, run migrations, and then run in IEX

{:ok, resource} = PostgresError.Resource.MapError |> Ash.Changeset.for_create(:create) |> Ash.create()
map = Application.get_env(:postgres_error, :map_bug)
# This will return the Jason Encoder error
resource |> Ash.Changeset.for_update(:bug_here, %{nested_map: map}) |> Ash.update()
# This will run as expected with no issue
resource |> Ash.Changeset.for_update(:update, %{nested_map: map}) |> Ash.update()

Expected behavior I expected to be able to use my defined update actions to take nested maps and update accordingly.

** Runtime

Elixir version
Erlang version
OS
Ash version
any related extension versions
